Abstract: The present invention relates to a co-purchase digital system. According to the present invention, a product to be purchased by a member is ordered to a producer in a co-purchase form by an intermediary. The producer produces the product and delivers it to the member. The operating profit generated during the course is redistributed by the members, the intermediary, and the producer to establish a virtuous cycle system. The virtuous cycle relationship is established for every member including the member, the intermediary, and the producer. Accordingly, the demand for the product needed by the member in online e-commerce and offline commerce can be grasped with this system. When the intermediary orders the product in quantity through the producer, the producer can lower the unit cost of production while producing the product in quantity. The purchase cost of the product can be lowered based on the lowered unit cost of production. The profit resulting from the sale back to the member is distributed to the intermediary and the producer by this system and the purchase members are given mileage. An initial member who used the product becomes an intermediary, receives a product inquiry from another member, and orders the product to the producer to establish the virtuous cycle relationship. As a result, the product cost burden can be lowered. Every member is given a fee and a mileage form, and thus product-related promotion and store costs are unnecessary and profit distribution can be fair and equal.

Title: PCB case
Inventor: JI YOUNG DOO
IPC: H05K7/14
Filed: 2020-03-30
Abstract: The present invention relates to a PCB case which enters a guide fin of a PCB between a plurality of evasion ribs formed at the bottom surface of a housing, and fills resin liquid between the evasion ribs of the housing to prevent moisture from being penetrated into the guide fin and to reduce a filling amount of resin liquid filled in the housing. The PCB case includes a housing in which a plurality of evasion ribs are formed at the bottom surface, and a substrate support projection is formed at the edge. A surface mounted component is formed in the housing. A PCB formed therein with a guide fin at a bottom surface opposite to the surface mounted component is placed on the substrate support projection. A filling amount of a molding resin liquid filled in the housing is reduced proportional to a cross-sectional area of the evasion rib by filling the molding resin liquid exposed to a top surface of the PCB so that the PCB is submerged in the housing which prevent moisture from being penetrated in a guide fin by the molding resin liquid. Therefore, a filling amount of a molding resin liquid filled in the housing is reduced proportional to a cross-sectional area of the evasion rib. Since the filling amount of the molding resin liquid is reduced, the molding resin liquid is saved and a manufacturing cost is reduced. A guide fin of the PCB having various shapes at different positions may enter between the evasion ribs by entering the guide fin between a plurality of evasion ribs formed in a sorting method. It is not necessary to separately manufacture a housing including evasion ribs corresponding to a shape of the guide fin. In particular, the molding resin liquid filled in the housing is exposed to an upper portion of the PCB. A thickness of the molding resin liquid is reduced by submerging the PCB. Further, when the PCB is damaged and fails, the PCB may be easily separated from an inside of the molding resin liquid to perform maintenance.
